The Lambek calculus L provides a foundation for categorial grammar in the form of a logic of concatenation. But natural language is characterized by dependencies which may also be dis-continuous. In this paper we introduce the displacement calculus D, a generalization of Lambek calculus, which preserves the good proof-theoretic properties of the latter while embracing dis-continuiity and subsum...

separation of ten sedative- hypnotic drugs was performed by rp-hplc using mixed micellar mobile phase. effect of temperature, type and amount of organic modifier in mobile phase on efficiency (n) and asymmetry factor (b/a) showed that, the appropriate conditions for a good separation were 35°c and 7% (v/v) butanol in mobile phase.  variations of selectivity factor versus butanol concentration, ...

In this study, stress and displacement functions of the three-dimensional theory of elasticity for homogeneous isotropic bodies are derived from first principles from the differential equations of equilibrium, the generalized stress – strain laws and the geometric relations of strain and displacement. It is found that the stress and displacement functions must be biharmonic functions. The deriv...

Actinobacillus actinomycetemcomitans is a gram-negative, facultatively anaerobic bacterium which is associated especially with aggressive forms of periodontitis. Contradictory results on the localization of the A. actinomycetemcomitans serotype-specific antigen have been reported. The aim of the present study was to characterize the A. actinomycetemcomitans serotype d-specific antigen. The anti...

In this paper, the closed form analytical expressions for the displacement field due to a cylindrical inclusion in a thermoelastic half-space are obtained. These expressions are derived in the context of steady-state uncoupled thermoelasticity using thermoelastic displacement potential functions. The thermal displacement field is generated due to differences in the coefficients of linear therma...

what counts as global health? there has been limited discourse to date on the ways in which country-level contexts may shape positioning in global health agendas. by reviewing japan’s response to the refugee crisis, we demonstrate a clash between rhetoric and action on global responsibility, and suggest that cultural and historical factors may be related to the ways of perceiving and acting upo...

Displacement-based methods are recognized as appropriate approaches to reach the goals of performance-based seismic design method. In the direct displacement-based seismic design method, the seismic yield displacement is applied as one of the important design parameters. In this paper, a new relation is suggested to determine the lateral displacement pattern at first yielding of eccentrically b...

Displacement mapping is a powerful technique for adding detail to three dimensional objects and scenes. While bump mapping gives the appearance of increased surface complexity, displacement mapping actually adds surface complexity resulting in correct silhouettes and no parallax errors. This paper presents the background to displacement mapping, current hardware implementations and how to use t...
